The German automakers keep on making more and more powerful sport-utes – some capable of pulling jumbo-jets and driving up buildings – with seemingly no end in sight. But for one owner, a stock Mercedes-Benz G55 AMG just wasn't enough to outperform his neighbor's Porsche Cayenne Turbo, so he had the engine swapped out for the 720-hp 5.5L supercharged V8 from the Mercedes-Benz SLR McLaren. The result? 0-60 in 4.2 seconds in a package that's rivaled in its exotic-engined brutality only by the long-departed Countach-powered Lamborghini LM002.

Of course there's only one place on earth that such a unique creation could possibly call home: Abu Dhabi, the same über-wealthy gulf emirate where the obscenely wealthy built Ferrari theme parks and drive $1.4 million hyper-exotics with $14 million license plates. Where else?

See it to believe it in the gallery below and in the video after the jump.
